Carbon dioxide level unprecedented in 15 MY… More evidence it’s not the climate control knob!avid Middl

by David Middleton, July 10, 2020 in WUWT

If the Earth was 3-4 °C warmer with a much higher sea level 3.3 million years ago, with about the same CO2 concentration, what does this say about the potency of it as a climate control knob?

The last time CO2 levels were this low, Earth was in the deepest ice age of the Phanerozoic Eon, the Pennsylvanian (Late Carboniferous)-Early Permian.

HIGHEST U.S. TEMPERATURES ON RECORD BY STATE

by Cap Allon, July 12, 2020 in Electroverse

Historical documentation destroys the man-made global warming theory.

While those in control of the temperature graphs are all too happy to fraudulently increase the running average, what they haven’t (yet) had the balls to do is rewrite the history books.

As Tony Heller uncovers on his site realclimatescience, NASA routinely cools the past and heats the present, so to give the illusion of a greater warming trend — and comparisons between old and new graphs instantly reveals this fraud:

In 1999, NASA’s James Hansen reported 0.5C US cooling since the 1930’s:

By 2016, the same NASA graph has eliminated that 1930-1999 cooling:

Decadal Climate Prediction? Might As Well Throw A Dice!

The WMO has collated global temperature projections from twelve different organisations, covering this year and the next five years. They were produced in 2019.

It is totally clear that there is very little agreement between any of them, other than a warm Arctic.

An unkind person might call them a waste of space!

Arctic Ocean changes driven by sub-Arctic seas

by University of Alaska Fairbank, July 12, 2020 in WUWT

New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.

The University of Alaska Fairbanks and Finnish Meteorological Institute led the international effort, which included researchers from six countries. The first of several related papers was published this month in Frontiers in Marine Science.

Climate change is most pronounced in the Arctic. The Arctic Ocean, which covers less than 3% of the Earth’s surface, appears to be quite sensitive to abnormal conditions in lower-latitude oceans.

“With this in mind, the goal of our research was to illustrate the part of Arctic climate change driven by anomalous [different from the norm] influxes of oceanic water from the Atlantic Ocean and the Pacific Ocean, a process which we refer to as borealization,” said lead author Igor Polyakov, an oceanographer at UAF’s International Arctic Research Center and FMI.

Although the Arctic is often viewed as a single system that is impacted by climate change uniformly, the research stressed that the Arctic’s Amerasian Basin (influenced by Pacific waters) and its Eurasian Basin (influenced by Atlantic waters) tend to differ in their responses to climate change.

Since the first temperature and salinity measurements taken in the late 1800s, scientists have known that cold and relatively fresh water, which is lighter than salty water, floats at the surface of the Arctic Ocean. This fresh layer blocks the warmth of the deeper water from melting sea ice.
